Abstract

Cerium dioxide nanoparticles (NPs) were synthesised using a novel precipitation procedure and their function explored in a range of applications. The impact of different factors on CeO2 NPs synthesis including temperature and reactant concentration were evaluated experimentally and optimised. The resulting nanoparticles (with an average size of 35 nm) was then characterised by a range of physical and spectroscopic techniques including dynamic light scattering, scanning electron microscopy in conjunction with energy dispersive spectrometry, X-ray diffractometry,Brunauer–Emmett–Teller isotherm measurement, Raman spectroscopy, UV-visible spectroscopy and X-ray photoelectron spectroscopy. A new nanoparticle synthetic route, the “frozen NH4(OH) cubes method”, was developed, resulting in a higher yield of NPs and shows much promise.
